FUNCTION
Ground. Connect GND pins together for proper operation.
Output Voltage. Output of internal switch. Connect OUT pins together for proper operation.
Open-Drain Flag Output. ACOK is driven low after input voltage is stable between minimum V_IN
and V_OVLO after debounce. Connect a pullup resistor from ACOK to the logic I/O voltage of the
host system. ACOK is high impedance after thermal shutdown.
Voltage Input. Bypass IN with a 0.1µF ceramic capacitor as close as possible to the device.
Connect IN pins together for proper operation.
External OVLO Adjustment. Connect OVLO to GND when using the internal threshold. Connect
a resistor-divider to OVLO to set a different OVLO threshold; this external resistor-divider is
completely independent of the internal threshold.
